King & Tuckfield review for XERO Order & Inventory Sync

Poor customer service. Emailed and received no answer. I then connected via chat and took a while for them to take note of it. Opened a new ticket disregarding any screenshots or descriptions I put before. Did no thorough investigation and came back after two days telling me something I already knew, washing their hands that it was a XERO mistake (clearly wasn't). I re-wrote on an email the issue and asked to escalate. I received a standard response that it will "take a while" and I should upload to XERO manually. We pay $20/mth for a product that doesn't work and has no solution, unless you sell without Duties and Tax.
